"feedback" : "# Exercise: fractal\n\n### Correctness\n- In `Triangles.drawRec`, the recursive case doesn’t construct the three sub-triangles; it only makes a single recursive call and changes the coordinates in a way that doesn’t match the required fractal subdivision (halving `y` values independently breaks the triangle geometry).\n- In `Triangles.drawRec`, the recursion does not reduce the triangle by using midpoints of the edges, so the drawn result won’t be the intended recursive triangle pattern for `n > 0`.\n\n### Suggestion\n- For the triangle recursion step, think about how to split one triangle into multiple smaller triangles: compute the midpoints of each of the three sides (between `(x0,y0)-(x1,y1)`, `(x1,y1)-(x2,y2)`, `(x2,y2)-(x0,y0)`) and use those points as new vertices.\n- Instead of only recursing once, consider which smaller triangles should be drawn at depth `n-1` (how many “corner” triangles are there after you connect the midpoints?).\n\n### Code Style\n- In `Triangles.drawRec`, avoid “magic” coordinate manipulations like `y0/2` etc.; introduce well-named midpoint variables so it’s clear what each point represents.\n- In `Boxes.drawRec`, you mix direct drawing (`g.drawRect` for bottom-left) with recursion for the others; it works, but for readability/consistency you could choose one approach and comment why that one square is handled differently.\n\n\n# Exercise: knapsack\n\nLlm Evaluation ist für diese Aufgabe deaktiviert.
